To all whom it may concern:

Be it known that 1, WILSON R. RUTHERFORD, a citizen of the United States, and resident of Baltimore, Ma land, have invented certain newand use Improvements in Internal Combustion Engine Systems, of which the following is a specification.

The invention is desified to an dply air and moisture to the int c manifo of an internal combustion engine system adapted for automobiles and it consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claim.

v e accompanying drawi represents a side elevation of an automob' e engine with its carbureter, radiator and intake manifold with my improvement connected up in the In these drawings 1 indicates the engine casing, 2 the carburetor, 8 the intake manifold,'4 the radiator and 5 the dash, these.

chamber {fiends through the piece 8 and preferably.

s passage hasm lateral branch receivin a short i 11 extending through the das 5 and b5 thereto by suitable nuts or other means re resented at 12. This nozzle has con with it a pipe 18 suitably supported in fittings 14 attached to the engine casing, the front end of said pipe being connected with the upper portion of the lagiliblai to amigo water or1 gag: therem. e r passage opens into the chamber and these passages 9 and-10 are disposed at diflerent mts' around the axis of the llpiece 8 and upper openin are contro ed by a disk valve 5 carried y a stem 16 extending vertically and substantially centrally of the to iece 8 and below said piece, the said stem avin a nut or finger piece 17 screwthrea ed onto its lower end with a spring 18 interposed between the said nut or finger pieces-11d the bottom of the member 8 so thatthe pressure of this spring can be ad-'- 'justed and its force tending tooseat the valve disk and close the openings 9 and 10 can be regulated at the will of the operator, it being observed-that the attachment is located at the instrumentboard or dash within con-. venient reach of the driver.

From the cap piece 7 of' the mixin chamber 6 a i e 19 extends centrally an upwardly an t is has a lateral branch 20 extending to the intake manifold and therefore to a point between the carbureter and the en e.

At t e junction of the vertical and lateral rtions of this communicating pipe 19, 20

- arran e a needle valve 21, which is-screwthreade through the pipe and extends axially in line with the vertical opening through the ipe 19 leading from the mixing chamber an it isadapte to a seat at the lower end of this vertical assage where it joinsthe lateral passage. is valve has a kerfed head by ,which it may be adjusted and set in difierent positions to regulate the size of thedischar opening between the mixing chamber an the lateral pipe 20. so In the operation of the device atmospheric 1 airtogether with vapor, moisture or water will be drawn into the mixing chamber 6 by the suetion created in the pipes 19 and 20 from the intake manifold, this suction action lifting the disk valve 15 and allowing the air and water or moisture to pass into the mixing chamber and this mixture then passes through the-regulating needle valve into the a pipe 20 the intake manifold andlthence to to v the com ustion chambers of the-engine. The

needle valve renders the appliance a'p-. plicable to en e systemsof diflerent make for by adgisting it the difierent conditions arism om varying suction as between the di erent makes may be met,

that in any case a proper lifting of the disk valve may be secured and the use of.

the spring 18 with the ad'ustable finger piece or nut 17 provide furt er regulatmg elements to control the operation of the. valve and by regulatin the pressure of the sgring the operation 0 the stem may be a 'usted to suit varying oreover, I mayuse 'iferent sizes of 105 nozzles to get difierent amounts of water, vapor or moisture supgly and the use of such nozzles will avoi 'disturbancesthat occur ordinarily from the use of the needle valve which under vibration is apt to lose 7 ing from the top of the radiator through the dash and Suitably supported from the engine casing nuts threaded on said pipe and clamping the dash therebetween, a cylindrica block having a port in its side threaded to engage the end of said pipe, said block having a flat upper face and a passage leading from said port to said upper face,

' an air passage extending vertically through said block, a hollow cap in threaded engagement with the upper end of said cylindrical block, said block havin a central passa e, a disk valve overlying tfie upper face of t e block and having a stem depending through said central passage, a nut on thelower end of the stem, a spring confined between said nut and the lower face of the, block, a pipe elbow having one arm connected to said cap, a screw valve in said elbow, and a ipe connecting said elbow with the .inta e manifold of the engine, substantially as described.

In testimony whereof I a x my signature. 1
